Original application filed January 11,

To aZZwwm t may concern: y

Be it known that l, SAMUEL J. VViLsoN, a. citizen of the United States,residing at Roberts, in the county of ,Jefferson and:

This invention relates to certain improvel ments in beet and. potatodiggers and eleva- .y tors, and it is an object of the inventiontoprovide a novel and improved'apparatus of this general characterincluding a revolving lifting'ineans and which means aresupported foryielding movement in a. .vertical plane to compensate forA 'tops'orcrownsof varying sizes.` v

The invention consists` inthe details of construction and in the'combination and arrangement of the several parts of my viniprovedvapparatus whereby certain rimportant advantages are attained and thedevice rendered simpler, less expensive and otherwise more convenientand advantageous for use, as will be hereinafter more fully set forth. Y

The novel features of my inventionwill hereinafter be definitelyclaimed. y'

In order that my invention may be the better understood, l will nowproceed to describe the same with reference to the accompanyingdrawings, wherein: l

Figure 1 is a fragmentary view in side elevation of an apparatusconstructed in' accordance with an embodiment of my invention; Y

Figure 2 is a view partly in elevation and partly in vertical section ofthe vertically swinging support frame as l'included in my invention asherein embodied;

Figure 3 is a fragmentary vie-W partly in section on the line 3-3 ofFigure 2 and partly in elevation, illustrating in detail a mounting forone end portion of the shaft of the rotary elevating means; and

Fi re 4 is a fragmentary View in topplan, illustrating the pivotalconnection with the vertically swinging frame with a Specification ofLetters Patent.

transverse member or beam comprised in the main frame. i

As disclosed in the accompanying ldrawings, Fdenotes' an elongated frameadapted to be supported in a conventional manner at its opposite endportions for travel over .the ground surface and preferablybyv wheels.The rear portion of the frame F isV also adaped to support a beetharvesting'inechanismvpreferably of a. type disclose-d in my priorPatent, No. 1,285,529, issued NovemberV 19, 1918 32 denotes diggingblades and 36 indicates a directing plow or'shovel as comprised in themachine as embodied in .the disclosure of that",patent. i

jThe forward end portions" of the side [members 1 ofthe frame Fareconnectedby the transversely disposed member or beam 2. rhis 'memberor'beam 2,1at'its central portion, ispr'ovided with apair of inwardlydirected fpald. brackets 321111,61 pivotally'engage@ With said `bracketsare' the v:forward end portions of the side members 1 of the verticallyswinging i is rdisposer'l downwardly' and rearwardly in a directionlongitudinally of the framev F andthe lower'or rear end portions of thelside members l thereof are provided with substantially 'verticallydisposedfarms 6 de` pending therefrom and with the upstanding arms Tina-ligninent'with the arms 6. The upper ends of the arms 7 are connectedby the transversely disposed member or beam 8. Each of the arms 6 isprovided with a longitudinally disposed Aslot S) in which is slidablyengaged an end portion of a shaft 10. The shaft 10 is disposed in adirection transversely of the frame F and fixed to said shaft 10 Ainlongitudinal alignment with the digging blades 32 is a rotary liftingmember R. The member R is in close proximity to the blades 32 and alsoin close proximity to but free of rcontact with the ground level. Themember R is preferably of a struct-ure disclosed in my priorapplication', Serial No.

frame S. The frame S soV for rotating the shaft l which meet-s therequirements of practice.

The ylower or rear ends of the side members 4 of the swinging frame S-arepr'ovided with the extensions 2l and engaged with each of saidextensions 21 is the lower end portion ofa vertically disposed rod 22,having itsv upper end portion loosely directed through the transverselydisposed member or beam 23 connecting the side members of 'the frame F.As herein disclosed, the lower Vend portion of the rod 22 is provided.with an enlarged eye 24 which is engaged with the extension 2l and'interposed between said eye` 24 and .the transversely disposed memberoi' beam 23 is an expansible member .25 hereinr disclosed as a coilspring enf/i1- cling said rod and which serves to urge .downwardlytlierear portion of the framev S but permits a yielding` upper swingingmovement thereof. v Y

Each of the rods 22 has engaged with the (upper endv portion thereof andabove the member or lbeam 23 a stop26 herein disclosed asa nut andcoacting washer and which stop serves to limit the downward movement ofthev rod 22 and consequentlyl A. the downward swinging of vthe frame F.'It

o will be self-.evident that-fthe tension of each 3Q of the members 25will be regulated by imparting longitudinalmovement tothe coacting-rod22 relative to the member or beam 123 and which adjustment maybeaccomplished by the stop 2,6. i y Each of the upstandinguarms 7 is proarequisite turning vmovementof f vided with an inwardly directed bracket27 having adjustably engaged' therewith and positioned therebeneath a'plate28`l Interposed between the plate 28 and the'adjacent bearing 29fortheshaft l() is an expansible member 30 herein. disclosed as a coilspring and which serves to constantly urge theA shaft l0 or moreparticularly vthe bearing 29 toward the lower end of the slot 9 in theadjacent depending arms 6 whereby the rotary lifting member R is furthersupported for yielding movement andindependently of the swinging frameS. y

" Froml the foregoing description, it .is thought to vbe obvious that anapparatus coi'istructed in accordance with my 1invention is particularlywell adapted for use bv reason of the convenience and facility withwhich it may be assembled and operated, and

it will also be obvious that my invention is susceptible of some changeand modification without departing from the principles and spiritthereof, and for this rea-son I doV frame pivoted at one end to the mainfi'amer said supplemental frame having arms depending from its oppositeend portion, said arms having `'registering slots? ,a shaft bearingslidable in each slot, springs yieldabl'y 'connecting the bearings tothesupplemental frame, and rods carried by the secondmentioned end ofthesupplemental frame, said rods beingl movablyeonn'ected to the mainframe.
